What kind of differential is a Posi track?
What kind of differential is a Posi track?
Posi-Track is a shortened generic term for the GM-branded name “Positraction.”. It is a type of limited slip differential. To understand how limited slip differentials or LSD works, you must understand how a differential works, and how it relates to torque. In basic terms, a differential takes the power from the output drive…
How does a Positraction unit prevent loss of traction?
Positraction units prevent loss of traction by sending power to both driven wheels. At the same time, each wheel rotates independently when necessary, preventing the non-slipping wheel from losing power.
When do you use Positraction in a differential?
Positraction In a positraction differential, the unit senses which wheel has the greatest traction, when one tire is slipping or stuck, and sends power to that wheel. Power to the other wheel continues until equal control is returned to both tires. Positraction is beneficial when road conditions are wet or muddy.
Where is the Posi track on a 4 wheel drive car?
It is found on the rear axle of a rear-wheel drive car, the front axle of a front-wheel drive car and on both axles for a 4-wheel or all-wheel drive car.
How does posi traction work?
Positraction . In a positraction differential, the unit senses which wheel has the greatest traction, when one tire is slipping or stuck, and sends power to that wheel. Power to the other wheel continues until equal control is returned to both tires. Positraction is beneficial when road conditions are wet or muddy.
What is a Posi trac or limited slip differential?
The Limited Slip Differential is a mechanism that shortens wheel rotation during driving. While driving, the wheels fail to grip and the power activates. This differential redistributes the power of the engine by holding as much as possible.
What is Positraction differential?
A posi-traction differential, also known as ATB (automatic torque biasing), is a simple and effective way to greatly increase your traction on and off-road. Unlike an “open” differential (i.e., your stock unit) that shifts power to the wheel with the least traction, an ATB senses which wheel has…
What is a Positive Traction differential?
Positive traction differentials, sometimes referred to as posi-tracs, or posi diffs, change the performance characteristics of a rear-wheel-drive car’s differential. The differential allows the rear wheels to turn at different rates when the car goes around a corner, and delivers drive force to the wheel with the least amount of resistance.
